A rescue equipment case remains in contact with the horizontal floor of a hot-air balloon basket.
The case has a weight of 480 N.
Gravitational field strength (ggg) = 10 N/kg
At one instant, the normal contact force exerted by the floor on the case is 432 N.
Calculate the vertical acceleration of the case, giving its magnitude and direction.
